WINDOW FRAME AND -SASH.

SPECIFICATION forming part of Letters Patent No. 511,409, dated December26, 1893.

Application filed May 22,1893. Serial No. 475,038. (No model.

T0 at whom it may concern.-

Be it known that I, AUGUSTUS H. COLE, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented a new and use-' ful Improvement in Window Frames andSashes, of which the following is a specifica tion.

This invention relates particularly to window frames and sashes inrailway cars and carriages, and it consists in the novel con structionand combination of parts hereinafter described, whereby rattling andvibration are prevented, and the general construction improved.

In the accompanying drawings, in which similar letters of referenceindicate like parts,-Figure l is a front elevation, looking from theinside, of a double sash window frame and sash embodying my invention,portions being represented as broken out to illustrate the improvement.Fig. 2 is a central transverse vertical section of the same, a portionof one of the stop-beads being repreented as broken out. Fig. 3 is ahorizontal section on line at, Fig. 2. Fig. 4 is an enlarged sectiontaken on the same line as that shown in Fig. 2.

A represents the sill, B the lintel, O D the upper and lower sashesrespectively, E the outer walls of the casings or jambs, and F F theinner and outer stop-beads respectively.

H is an upright or post set vertically within the jamb between the rearstop-bead F and the outer wall E at the rear of the sashes. The frontinner corner of this upright is removed to receive the edge of the uppersash O, as shown in Fig. 3.

I is an upright set vertically between the front stop-bead F and thewall E in front of the sashes, but not extending far enough rearward tocome in contact with either sash.

The lower sash D extends between the upper sash and the rear edge of thefront stopbead F, as shown in Fig. 3, and almost to the outer Wall E.There is, hence, quite a space between the run of the lower sash and theupright I. See Figs. 2, 3, and 4. Within this space are two or more freecylindrical rolls K made of rubber or other analogous elastic substanceor composition. These rolls are set with their ends toward the bead Fand easing, substantially as set forth.

wall E, and their diameter being normally somewhat greater than thedistance between the upright I and the sash D, they are contractedsomewhat in their present position by being between said upright andsash, and hence operate to press the lower sash closely back against therear stop-bead F and the upper sash. The rolls, of which there are shownin the drawings three on a side, rest when at their lowest points onledges or supports L L L, and when the lower sash D is raised they rollup between it and the upright I, offering practically no resistance tothe movement of the sash.

In order to prevent the rolls from falling out, a thin vertical bead orstrip e is secured to tillie wall E opposite the edge of the lower sasThe upright I is made in two parts, joining, preferably diagonally, atI, as shown in Fig. 2, in order that the sash D may be removed byslipping out the lower section of the upright.

Any suitable contrivances may be applied to the lower sash, whereby itmay be lifted and locked, it not being deemed necessary to illustratesuch in the drawings.

In order to prevent dust from settling in the lower ends of the spacesbeneath the extended edges of the lower sash, the sill is built up on anincline at a (Fig. 1), and the lower sash is made at its lower corners Dof corresponding shape. This incline tends to cause the dust to slip outof the space, which is necessarily deep for the purpose of accommodatingthe rolls and the extended edges of the sash.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a window frame and sash, the combination of the frame or casingprovided with.

an internal vertical chamber or space extending in front of the sash,the sash extending into the rear portion of said space, and afree rollof rubber or analogous elastic material within said space and pressedbetweenthe front surface of said sash and theframe or 2. The hereindescribed window frame and sash, comprising the jambs consisting of theouter walls E, rear and front uprights H I,

rear and front stop-beads F F, upper sash sill provided with theinclined or beveled extending into a suitable recess in the cornerblocks a within said spaces and inclining of the rear upright H, lowersash extending down toward the window, and the lower sash into avertical chamber or space between the having its lower corners D beveledto corre- I 5 5 rear and front uprights, and free rolls K of spend withsaid blocks, substantially as set rubber or analogous material pressedbetween forth.

the lower sash and the front upright and free to roll as the sash ismoved in the frame, sub 7 AUGUSTUS COLE stantially as set forth.Witnesses: I0 3. The combination of the jambs provided HENRY W.WILLIAMS,
